TYPE-WRITING MACHINE.v

SPECIFICATION forming part of Letters Patent No. 330,l83,dated November 10, 1885.

Application filed November 14, 1884. Serial No. 147,967. (Model.)

To all whom it may concern:

Be it known that I, TIMOTHY WILKINs, a citizen of the United States of America, residing at Sigourney, in the county of Keokuk and State of Iowa, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.v

This invention pertains to improvements in type-writers, more especially in appliances to adapt the latter for use in writing in books, while it is equally applicable for writing upon separate sheets of paper; and it has for its object to effect the foregoing purposes in an expeditious and approved manner.

The invention consists in the sundry combinations of parts and their construction substantially as hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is a plan view showing my invention as applied to the leaf of a book. Fig. 2 is a detail view of the appliance for adjusting the type-writer .over the face of the paper or book with its cover removed. Fig. 3 is an under side view thereof. Fig. 4 is a cross-section taken on the line x zo, Fig. 1. Fig. 5 is also a sectional View ofthe same, said section being taken on the line y y, Fig. 3; and Fig. 6 is a detail view -of the paper-clamp with parts broken away.

In the organization of my invention I employ an inclosng-case, A, which is preferably `constructed with la rectangular chamber, a, at

`its inner side to receive the rack-bar B, the .purpose of which will appear further on. rIhe ,chamber a may be provided upon its lower and inner sides with movable lining-plates b b', withbent ends to secure them as against longitudinal displacement. Along the lower linner edge of one side of the case A is formed a horizontal ledge, d, to which an extension of the under side plate of the case A is bolted or fastened. In each end of the thus bolted or fastened together ledge andplate extension are cut notches or slots e, the function of which will appear further on.

O is one of the end bars, to which are connected the carrying-rods and graduated plate 5o. of the type-,write r, as shown, which latter form no. parte `of this invention, and need not therefore be here further described. To this end bar of the aforesaid carrying-rods and. plate is connected the case A, a thumb-lever, lD, being eccentrically pivoted in a slot, f, in said end bar, O, with the heel of its eccentric bearing upon a spring, g, secured to said bar in the bottom of said slot, while the front edge of said eccentric fits into one notch or slot c of the ledge d, and an overhanging hook, h, formed or brazed upon one end of the end bar, O, fits into the other slot or notch e of said ledge. This eccentric or holding lever effects, together with said overhanging hooki, as will have been observed, the removable connection of the case A with said end bar, O, of the typewriter carrying rods and graduated plate. The action of the spring g locks the lever l) in place when depressed into contact with the ledge d, into which position said lever is placed when the case is connected to the aforesaid end bar. the case Ais disposed a pinion, E, whose teeth engagewith the rack-bar B to cause the forward or backward movement of the type- Within the outer end chamber of l .w riter, and which pinion is fitted upon a shaft,

.beyond each side of the case A, its lower end having parallel slots or notches j, which receive the side edges of the slot or yoke la of a lever, F, with one end pivoted to the under side of the case A, near one edge.

said case A upward, to permit its convenient Ymanipulation by the hand, thumb, or nger.

By the movement of the lever F into engage ment with the slots j of said end of shaft or spindle E the collar i of said shaft is moved in the recess i of the pinion E, forcing or clamping said pinion upon a friction-pad, l, in the bottom of the case A, thus holding said pinion firmly as against movement, which is desirable when the type-writer is in operation, or after it has been properly adjusted. Previous to the transmission of movement to the pinion E the lever F is moved out of contact with the pinion shaft or spindle E. Upon the end of the spindle or shaft E is fitted, so as to The free end of the ,lever F is bent beyond the opposite edge of IOO m, extending into slots lmin two semicircular` frictional clutches, H. r)The opposite straight edges or surfaces of the clutches H are provided with recesses u, for reception and retention of springs n', which normally hold the clutches into forcible contact with the pinion E, the clutches being seated in a recess or dfb-' pression, fn?, of said pinion. The slots m of the clutches H are disposed obliquely 'to radii of the circle described by the joint outer edges i of the clutches, whereby, upon turning the bar, to enable the type-writer to again knob to the right, said clutches are so acted upon by the pins or studs of said knob as to permit the compression of their springs and the retraction of said clutches from contact with vthe shoulders of the recess of said pinion, Within which said clutches are disposed, as above stated, and thus permit the reversal of the movement of the`pinion as is required to return the case to the upper end of the rackbegin operation.

I is an adjusting and holding screw working in a bracket, i2, secured to the case A, theinner en'd of said screw being adapted to bear upon al flattened or plane surface, 3, formed upon the shank of the knob or hub G.

From the foregoing it is obvious that, by varying the adjustment of said inner end of the screw with relation to said surface of the knob-shank, (it being understood, of course, that said screw is not to be moved beyond contact with said knob or hub shank,) the amount of movement to be imparted to the pinion E can be-regulated, givingitmore orless, according to the distance it is desired to move the case with the type-writer, in order to vary the spacing between the lines of writing.

To properly or flatly hold down the leaves;

of a book upon which the type-writer is to be placed or adjusted for writing therein, I provide a board, J, which is provided with twoparallel suitably-spaced-apart slots, J', being governed as to the amount of space to be left between them by the width of the leaves of the book. These slots have their sides beveled or inclined from the upper surfacefof the board outward, to permit the proper insertion or reception of the leaf .of the book. Toapply the board to the leaf of the book, the former is stood upon its lower left edge, slanting over the book, when with one hand or three fingers the lower left corner of the;

leaf is in the present instance passed into and, through the righthand slot of the board. The; board simultaneously with the continued pass. ing of the leaf through said slot is moved over onehalf of the book. The leaf, after having, been passed sufficiently through said slot upon. the board, is next passed through the other slot of the board, when the-board with the leaf will be brought to a horizontal position,

resting upon the book.Y Thepaper is noW J Said paper-clamp consists of a long thin metallic plate, K, having its ends rounded to provide a pivotal support or bearing for and to .permit the operation of said plate, and it is also provided with a stem, 7c, extending down- Wardly through a'slot formed in the board J, and said stem is clamped at its lower free end by a keeper, lc. Sai-d keeper is passed through. a slot formed in the surface of thel under side of said board J, and extends a short distance beyondrthe Aupper edge thereof, where it is provided with a suitable head' or knob, ltol permit of its easy manipulation. Asmall Alng or projection, l, is formed or cast integral with the upper surface of said keeper, andi-is secured in a small slot or recess, Z', formed i-n said board', and: by this arrangement the keeper is guided in its-movement. Thefinner endof the-keeper lo is provided with a small shank, Z2, designed to be projected through a slot formed ynear theiloweredge ofthe stenik, and said shank is encircled by a small.' coil-spring, k2, the other end of which presses against the surface of the slot formed in the board J, and the office of said spring, it is obvious, is to lregulate the actionof t-he-paper-clamp. The

IIO

to havebeen applied to the board as-above described, the caseA is moved bytheope'rator to the topfof the rack-bar B, and. the thumb-l lever D being opened or in a raised position the; connecting-bar of the type-writer is so placed alongsidev of the said case A as to-cause i Jthe hook k and'thefront edge vof thefsaid eccentric to fit into the notches or slots e e of the ledge d, and by closingor pressingdownwardly on-said thumblever the same will effect the secureconnection of theV case A. Then byv turningthe-knob or hub-O of the spindle-or shaft E ythe' same will'cause the turning of the pinionE, engagingwith the rackbar B,

luntilthe gagebar andtypecarriage `are 4in the'desired position on"theleaf of`thebook, and thecaseand the type-writer areheld in such position by pushing outwardly ontlel'ever F,

The adjustment screw opposite the attened/or/planer-surface i3 formed on the shank of the said knob or hub the same will regulate the distance between each line of Writing.

It will be observed that when the device is in the position just detailed the revolution of the pinion E is only effected by turning the knob or hub to the left, and that after each adjustment of the type-Writer in the desired position the knob or hub is turned to the right, thus also returning the clutches ready for another adjustment of the type-Writer, as before stated.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent is- 1. The combination of the fixed rack and the pinion connected With the type-Writer carrying-frame, and fitted upon a loose spindle or shaft having a iixed collar entering a recess of said pinion,with the lever having a yoke or slot receiving and connecting with said spindle, substantially as shown, and for the purpose described.

2. The fixed rack and the pinion engaging the rack mounted upon a loose spindle or shaft,andconnected,substantiallyas described, with the type-Writer carrying-frame, in coinbination with the frictional clutches tted within a recess of said pinion and a knob to turn said spindle or shaft having pins engaging the clutches, substantially as shown, and for the purpose described.

3. The fixed rack, the pinion mounted upon a loose spindle or shaft carrying a knob or hub provided with pins or studs, and connected, substantially as described, With the type-Writer carrying-frame, in combination With the frictional clutches disposed Within a' recess of said pinion, and having slots ob liquely arranged to radii of the circle described by the outer edges of said clutches and receiving pins on .the knob, substantially as shown, and for the purpose described.

4. The fixed rack, the pinion together With its loose spindle, and the frictional clutches having oblique slots, in combination with the knob or hub having pins or studs engaging said slots of the clutches, the holding and adjusting screw engaging a straight or flattened surface of the shank of said knob or hub, and the type-Writer carrying-frame connected,substantially as described, to the spindle of the pinion, substantially as and for the purpose set forth.

5. The combination, with the type-Writer carrying-frame comprising rods and end bars, one having au overhanging hook, of the adjusting mechanism with its inclosing-case provided With a ledge having slots or notches in its ends, and the eccentric lever acted upon by a spring disposed in one of said end bars, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two Witnesses,

TIMOTHY WILKINS.
